1. cusp- Package for applying Cobb's maximum likelihood method to fitting cusp catastrophe models to data. The package was published in the Journal of Statistical Software [see www.jstatsoft.org/v32/i08/paper].

4. spatial copula- This package is intended to provide the power of copulas to the spatial and spatio-temporal context. It will offer tools and functions to perform spatial analysis exploiting the possibility to fully model the whole dependence structure with copulas.
